I have had my small pan for at least 6-8 months. I have cooked just about everything I can think of in it. I use oil and butter and also nothing at all on occasion. I put it through the dishwasher, I have added water to it while its hot, Ive done about everything people say not to do and its still going strong.
Keep in mind that things will stick especially if you arent using oil or butter in it but its sooo easy to clean afterwards its not even funny. If you cook your foods on medium and below heat the sticking is minimal and again, you can usually wipe it out with a paper towel and its clean and ready to be used again.
I did order the big pan and lid from amazon and then I see these on here lol. Oh well, one thing to note I guess, I cook on a gas stove so other ways may differ in their results.
